Which term is best defined as performing an experimental run multiple times by completely breaking down the setup between runs?

Repetition
Parallel Experiments
Replication
Sequential Experiments

The correct answer is: Replication

The term that best fits the description of performing an experimental run multiple times by completely breaking down the setup between runs is replication. Replication involves conducting the same experiment more than once to assess the variability of the results and ensure the reliability of the findings. By completely resetting the setup between each run, researchers can eliminate any carryover effects from previous trials, which may influence the results. This approach enhances the validity of the experiment by confirming that the outcomes are consistent and not artifacts of a particular run. The focus on repetitively conducting the same experiment under identical conditions distinguishes replication from other terms. For instance, while repetition might imply running the same experiment multiple times, it doesn’t necessarily mean that the setup is completely rebuilt each time, as is the case with replication. Parallel experiments refer to running different experiments simultaneously to compare results, which contrasts with the sequential and isolated nature of replication. Sequential experiments involve conducting experiments in a series but do not inherently require a complete breakdown of the setup between runs like replication does. Thus, replication is the most precise term for the scenario described.
